1t is well understood that a cold
sensation reaches consciousness more
rapidly than one of warmth. The ex-
act time required to perceive each has
lately been measured by DR.. Gold
schneider, of Berlin. Contact with
cold point was felt on the face after
1875, on the arm after IS. on the abdo-
men after %, and on the knee after %
hundredths of a second. From hot
point the sensation was felt on the
same surfaces after 10, q, 26 and rs
hundredths of second respectively.
This great time difference has an i'm
portant bearing on the theory of skin
sensations. -ArkdnsGW IraUeter.

Small air bubbles are not infrequently
observed in hot weather, but these
were seen rising from the snow in JAN
uary and were of the same size and
shape as the toy balloons so commonly
sold on city streets. They rose to Il
considerable height and then began to
move up and down within a limited
area and at equal distances from each
other, some ascending aud some de-
scending." The first flight lasted about
two minutes, when it was followed by
another of similar character. All the
bubbles fioated off in an easterly direc-
tion.-N Y Ledger.
